I can understand how you got the name from "metal" and Futurama. But in the UK, "bender" basically means "faggot". Maybe you might want to think on the name,/. https://en.wiktionary.org/wiki/bender
Because there's plenty of slang that doesn't inhibit use of the word by its earlier definition. Nobody blinks when you ask for a "box". Teenagers might giggle at Dick's stores, but it hasn't hurt business.
